[Qgis-developer] Suppress rendering of small features

[aperi2007]

Not always is preferrable to suppress the small features.
Often in our rendering we prefere to substitute a small rendering of 
kind polygon with a point rendering at lowest scales.

This is possible using the Rule-Rendering
also is possible to use the rule-rendering to define a rule that in a 
scale interval and with a dimension interval the feature is render using 
a point rendering and change in a polygon rendering when the scale grow.
